' Application filed May as, 1927. Serial No. 193,982.

The invention pertains to attachments for use on twin faucets of thecharacter found in kitchen sinks and elsewhere, one faucet ordinarilybeing designed for the delivery of cold water and the other for hotwater. The attachment of my invention may be conveniently applied to andremoved from the faucets and maybe used for drawing cold water aloneorhot water alone or hot and cold water commingled.

One object of the invention is to provide an attachment which may, withentire convenience, be appliedto and removed from the faucets, and whichwill assure the commingling of the on a discharge of the same the watermay have the desired temperature.

A further purpose of the invention is to provide an attachment which isadjustable to the spacing or distance'between the faucets.

A still further object of the invention is to provide an attachmentwhoseparts may be readily assembled without the use of screw threads andapplied to the faucets in a manner to avoid leakage.

The attachment of my invention comprises a main transverse tube having adelivery spout extending therefrom, two tubes telescopically appliedwithin the ends of said transverse tube, certain cups mounted on the endportions of the last-mentioned tubes and adapted for direct applicationto the faucets, and stirrups detachably' engaging the outer portions ofthe telescopically applied tubes and the faucets for firmlymaintainingthe relation of the aforesaid cups to the faucets, thesestirrups resisting the action of the water in forcing the said cups andthe attachment as a whole downwardly from the faucets.

Another object of my invention is, therefore, to secure the continuousproper relation of the attachment to-the faucets and to overcome whathas been a serious objection to the employment of attachments of thecharacter made the subject hereof.

A- further object of the invention is to secure such strength andrigidity in the portions of the attachment that the strains exertedagainst said portions during the ap plication of the attachment to thefaucets may not strain or break off the end cups from the ctherportionsof the attachment The invention will be fully understood from thedetailed description hereinafter hot and cold water so that endpresented, preference being had to the accompanying drawings, in whichFigure 1 is a front elevation, partly in section, of the attachment ofmy invention shown applied to a pair of faucets;

Figure a is a transverse section through the same taken on the dottedline H, Fig ure 3, and

- Figure 5 is a detached perspective view of one of the stirrupsemployed by me for maintaining the attachment in proper relation to thefaucets;

Figure 6 is a front elevation, partly in section, of a modified form ofthe attachment of my invention;

Figure 7 is a vertical section, through the same taken on the dottedlines 7-7, Figure 6, the movable portions of the attachment being shownas being moved back against the wall, and said parts being shown bydotted lines as drawn forwardly, the dotted lines also showing how thedischarge spout of the attachment may be turned from a lower position toa more elevated position, and also that the nozzle portion of thedischarge may be turned angularly so that the discharge orifice pointsupwardly instead of downwardly.

The attachment of my invention comprises ainain transverse tube or pipe10 having a nipple or short tube section 11. extending centrallytherefrom and at a right angle thereto, a discharge spout 12 mounted onsaid nipple, two branch tubes 13, 14;, respectively, telescopicallyapplied to the opposite ends of said pipe 10, and cups 15, 16,respectively, rigidly mounted upon the outer end portions of said tubes13, 14 and extending upwardly therefrom and at a right angle thereto,saidcups 15, 16 being adapted for application to the faucets 17, 18,respectively, which are of customary type.

The transverse tube or pipe 10 may be called a main tube and liestransversely between'the vertical planes of the faucets 17, 1S, and mayreceive water from either or both faucets. At its central portion thetube 113 has permanently extended therefrom. the

. enlargements 19 as shoulders and r tened outer end 21,,and otherwisesaid spout is cylindrical in cross-section and at its inner' endisformed with anenlargement 22.

containing a rubberflat band gasket 23,

. which abuts against the-inner end of the enlargement 22 as'a.shoulderand projects-outwardly to a limited extent beyond theouter edgeof said enlargement. The spout 12 is pushed upon the nipple 11,,saidnipple extending into the spout beyond the inner end of the enlargement22, as shown in Figure 2;. The gasket 23forms a liquid-tight jointbetween the inner endof the spout 12 and theouter. surface of the nipple11. The s out 12 may be turned angularly on the nipple 111, so that itsdischarge end 21 may project downwardlyasshown in Figure '2 or upwardlyor laterally or on angular lines to the vertical, asn ay be desired.Should itbe'desired' to drink from. the spout 12, said spoutmay beturned on the nipple 11 soithat the outer end 21 of the spout projectsup wardly,.this position of the spout rendering it convenient for aperson to drink there-' from; The tube or pipe 10 may be turned on itslongitudinalaxis, and hence the spout 12 may be deflected upwardly ordownwardly as may be desired. The spout 12 is also detachable from thenipple 11.

The cups 15,16 are alike in general construction and each comprises anintegral metal shell vertically disposed and having a lateralenlargement 2% around its upper edge adapted to form a seat for anenclosed vertical packing band 25,.which has an open center, anenlargement at its upper end fitting the-enlargement 2 1-: of the cupand a depending portion having downwardly converging outer surfaces, asshown in Figure 3. The packing band 25 is of considerable height. and isforced into the upper end of the cup so as. to form a tight fit therein.

Upon the enlargen'ient '24. of each cup is placed. a cap 26 which has anopen center and isdished downwardly at its top, which is firmly'pressedagainst the upper surface of? the packing, bandr25. The cap 26 issecured upon the upper end of the cup by a bayonet-joint connection,wardly extending studs 27- (Figure 1) on the vertical edge of theenlargement 2-1 and an annular groove 28 in the skirt of the cap 26 bevery firmly the force of the discharging there being out-' 16 inapplying them to;

to receive said studs, openings 29 being formed in the skirt of the capto be pushed downwardly over the studs 27, whereupon by turning the cap26 011 the enlargement 24, said openings'29 are carried from the studs27 and the studs are caught within the groove 28. r In this manner thecap 26. may fastened upon the: cup and against the packing band 25 andmay, when occasion requires, be readily removed from the cup. In thecup. 16 intended for the cold water faucet, I preferably providefiltering n' aterial 30, placed upon a perforated plate v31, forfiltering the water passing through the cup to the discharge spout. Thecup 16 isfori'ned'with an annular groove 32 which createsan internalbeading on which the perforated disk 15, 16 arepushed upwardly upon thedischarge members of the faucets 17, l8, and by the means hereinafterdescribed said. cups are held upwardly onsaid discharge mem; bers undera pressure which helps to create a liquid tightjoint between the packingbands 25 and. the faucets and also prevents water from'the faucets fromdislodging thecupsffrom the faucets. The caps therein which are'largerthan the diameter of thedischa-rge members of the faucets and thereforesaid caps do not contactv with the metal of the faucets. a

' The tubes 13, 1d are alike except t-hat they project in oppositedirections and they slid ably enter the opposite ends of the maintube orpipe l0,a liquid-tight joint between the tubes 13, let and the tube 10being created by the packing bands 20.. The tube 13 has secured upon itsouter endthe cup 15 and the manner of'securing the cup tothe tube 13 isof importance in providing a durable structure capable of long use Theouter end of the tube 13 extends transversely through the lower portionof the cup 15 and isclosed at its outer end by a cap 33 (Figure l) andsaid tube 13 within the cup 15 is perforated, as at 3 1, to permit thewater entering the cup to freely flow into the tube 13 and thence passto the tube 10 and spout 12. The tube 13 and cup 15 are thus rigidlysecured together, and in this'instauce both opposite vertical walls ofthe cup are mounted on and securedto the tube 13, as distinguished fromthe inner vertical'side of the cup being soldered to an outer end ofatube l3'which would terminate at said side. By. carrying the tube l3entirely througlrthe cup 15; I secure a structure of great durability.and in which during the use of the attachment thecup is not liable to bebroken from the tube. With careless or ordinary handling a great deal ofstrain comes upon the cups 15, and removing them from the faucets andwith my'construction this strain is resisted by the fact that the 31maybe seated. The cups 26 have central openings- Hill llO

tube extends entirelythrough the cup and has two opposite point-s ofattachment there- 13. The tube 14 is rigid with the cup '16 in the samemanner that the tube 13 and the cup 15 are rigidly secured together.

The cups 15, 16 being rigid with the tubes 13, 14 respectively, may beadjusted laterally, due to the sliding action of the tubes 13, 14 in thetube 10. to suit the the spacing between the faucts 17, 18, there beingat times some differences as to the spacing between faucets. i

The method of applying the attachment to the faucets will be apparentfrom the drawings, the cups 15, 16being forced'upwardly on the dischargemembers of the faucets.

In order to firmly retain the attachment on the faucets and to secure aconstant pressure tending to draw the attachment upwardly on thedischarge membersof the faucets, I provide the stirrups 37, 38 which areof wire and have hooked upper ends 39 to engage over the back portion ofthe faucets, as shown in Figure 2, and lower hook members 40 to engageunder the outer portions of the tubes 13, 14. The stirrups 37, 38 are ofsuch length that when the hooks 40 are engaged on the tubes 13, 14 andthe hooks 39 are to be applied over the upper rear portions of thefaucets, some force is required to push said hooks 39 upon the fancetsso that after the stirrups 37, 38 are in place, they act under thespring tension of the upper hooks 39 to pull against the tubes 13,14 andvery firmly and securely connect the attachment with the faucets. Thehooks 40 are at right angles to the books 39 and lap around the frontsurfaces of the tubes 13,14. The hooks 39 are curved and there is enoughspring action in the wire of which the stirrups are madeto permit saidhooks 39 to be sprung over the upper rear portions of the faucets. Igive the free ends of the wires at the hooks 39 reverse bends, as at 41,and thereby form thumbpieces which facilitate the detachment of thestirrups from the faucets whenever it may be desired to remove theattachment therefrom. It has been found that in the absence of thestirrups 37,

38, the tendency of the attachment is to settle downwardly both of itsown weight and by the force of thewater issuing from the faucets andacting to create a down pressure tendency of the attachment to loseitsposition or be forced therefrom by the pressure of the water, is thepurpose of the stirrups 37,38, the pressure ofthe stirrups also actingto keep the packing bands 25 against thecups 15, 16, and to resist this.

firmly against the discharge members of the faucets and preserve watertight joints at said members. The stirrups 37, 38 also tend to resistany downward strain that might be exerted on the tube 10 by the pressureof the hand of a person drawing water from the spout 12.

The attachment is adapted to be adjusted. to the spacing between thefaucets and provides a rigid securing of the cups 15, 16 to the tubes13, 14. The cups 15, 16 in their construction are durable and welladapted to receive the packing bands 25 and be properly applied to thefaucets. The spout 12 is capable of adjustment both longitudinally andangularly, and the attachment when secured .in position on the faucetsby the stirrups 37, 38, becomes a very firm structure capable ofefficient use and of maintaining its correct position.

The modified attachment illustrated in Figures 6 and 7 comprises twoapproximately Z-shaped branch tubes 12 13 respectively, connected attheir upper horizontal ends with a coupling 14 having a branch nipple 15extending outwardly at a right angle thereto and upon which is applied aright-angle tubular coupling 16 upon whose outer member 17 is attached adischarge spout 18*, whose outer end is curved and contains a dischargeorifice 19*. The nipple 15 is rigid with the coupling tube 14 and atabout the middle of the length thereof, and said nipple has smoothexterior surfaces upon which may be closely slid a rubber gasket 20*heldwithin a tubular formation or sleeve 21 which is rigid on the member22 of the angle coupling 16*. The gasket 2O is so firmly compressedwithin the sleeve 21 as to remain therein by friction, and said gasket,while closely engaging the nipple 15, so as to prevent leakage aroundthe same, may be slid forwardly and rear wardly upon said nipple so asto adjust the angle coupling 16 toward or from the coupling 14*, as theoccasion may require. The angle coupling 16 may also be slid ofi fromthe nipple 15*, when desired. The discharge spout 18 is tubular and atits inner end is formed with an enlargement or sleeve 23 carrying arubber gasket 24, adapted to closely engage the exterior surfaces of themember '17 x of the coupling 16 and prevent leakage around said member.The gasket 24 has a sliding fit upon the member 17* of 1 the coupling16*, and hence the spout 18* may be adjusted along the length of saidmember 17, as may be required. The member 17* of the coupling 16 is ofsuch diameter that it may pass into the spout 18 out- 1 wardly beyondthe gasket 24*, as shown in Figured", and likewise the nipple 15 is ofsuch diameter that it may pass into the member 22* of the coupling 16inwardly beyond the gasket 20, as shown in Figure 7.

' the coupling 14* kets 27 28 orifice 19 as shown by the dotted lines inFigure '7, and "it being convenient to take a drink from theare-stationary the coupling 14* The coupling l6 may be turned angularlyon the nipple 15 either to the right or left, as may be desired, forswinging the dis charge spout l8 to one side or the other, as theoccasion may render convenient. The discharge spoutlS may, in anyposition of the coupling 16, be turned angularly on the memberl? of saidcoupling so as to locate the discharge orifice 19 -in such position asmaybe found mostconvenient. The dischargespout 18*maybe given a rotationon the coupling 16* to position thedischarge upwardly instead ofdownwardly,

discharge orifice 19 when saidoriiice faces upwardly. V

The coupling ll extends transversely between the faucets and'has on'itsouter ends the enlargements or sleeves 25*, 26, respectively, containing:rubber gaskets 27 28*, respectively, corresponding with the gaskets 2024*, hereinbefore described. The gaskets 27*,28" are rigid within thesleeves 25 26 and engage theupper horizontal branches 29 respectively,of the membcrs 12*,13 said branches 29*, 30* extending toward each otherand entering the opposite ends of and leakage around said branches beingprevented by the gaskets 27 28X'.'

It will be obviouson'reference to Figure 6 thatthe branches 29*, 30 maybe adjusted toward and from each other in accordance with the spacingbetweenthe faucets 10*, 11. The branches 29 30 may also be turnedangularly or on their ownaxes within the gasand coupling 14*. It will beobvious also that when the branches 29", 30* may be turned on them so astolocate the coupling 16*and spout 18 in any desired position.

he members 12*, 13* have the upper branches 29*, 30 downwardly andinwardly diverging body members 31 32 respectively, and lower outwardlyextending hori zontal branch members33", 84*, respectively, and said:members 33*, 34* entercorrespond- .ing metallic cups 35286,respectively, which are connected to the usual faucets 1O and 11% andare formed with laterally extending sleeves 37*, 38*, respectively,containing gas lcets 39*, 40*, respectively, through which the branchmembers- 33*, 34* extend and within which said members are capable ofrotation or axial' movement. 1 The gaskets 39*, d0

prevent leakage around the tubular members 33x 94x p z e) 7 andpermit'said members to head 1usted laterally in a direction toward andwhen the other portions of the attachments are being adjusted as toposition."

In Figures 6 and 7 I haveshown by full lines one position of the parts of the attachment, and inthis position the main branch members 12*- and 13* have been pressed attheir upper ends toward the wall, and this has 7 located the'coupling14: adjacent to thewall; as shown in Figure V In this po ition of theparts I have turned the coupling 14* upon the b'anch members 29 30 so asto turnthecoupling 16" down wardly'and position its member 17* and thespout 18 in a horizontal lower position, as shown by solid lines inFigure-7. In many of the several parts of the attachment shown in Figure7 will be entirely convenient for use. If, however, the occasion rendersnecessary, the branch members 12*, 13* may be swung forwardly at theirupper ends and thuscarry the con pling 1.6 and discharge spout 18forwardly to such position as may be found convenient, a widerange ofadjustment on'the linejust indicated being permissible. Whenever desiredthe spout 18 may be turned axiallyon the coupling member 17* so as tocause the discharge rifice 19 to point toward the right or toward theleft, or upwardly, as occasion may suggest. The branch tubes 12*, 13 mayalso be carried or'swun'g forwardly to a considerable extent, as :shownby the dotted lines in Figure 7, andat this time the coupling lfi 'maybe. turned forwardly and upwardly at its lower portion to thepositionshownby the lower dotted lines in Figure 7, thus causing-thedischarge spout 18 to be inclined upwardly and forwardly. Inthisposition of the'discharge spout shown by the lowerdotted lines in Figure7, said spout maybe-turned angularly on the coupling member 17 to directits discharge orifice 19 either to the right or left or up-J wardly, asmaybe desired. 7 r I r A further position that may be' given to"shownby' the'upper dotted lines in Figure i, wherein it may be 1-1" andprojects the discharge spout '18*forwardly, in which position said spoutmay be turned angularly" "COClllBClLllJS orifice gaskets 41 preventleakage r rendering the attachlnent adaptableto different conveniencesand se en'thatthe coupling 16* has" been turned to the upper side of thecoupling are tubular and contain iii? either upwardly or downwardly orlaterally, as may be preferred. The parts of the attachment permit ofgreat flexibility of'adjustment and enable the discharge spout 18 tohave many positions other than those indicated in the drawings. Forillustration, if the couplingh'e and discharge spout 18* should be inthe position shown by the upper dotted lines in Figure 7, the branchmembers 12*, 13* may be swung rearwardly against the wall and thus leavethe discharge spout in an elevated position above that in which thespout is shown by solid linesin Figure 7, and at this time the spout 18may be i turned angularly .to direct its orifice 19 either downwardly orupwardly or laterally to either side, as may be desired.

The metal cups 85 36* will preferably be used as filters, and each cupis formed with an annular beading 50 to support a perforated disk 51upon which will be placed a pad 52* of raw cotton through which thewater will pass from the faucets and which will serve to arrestimpurities that may be in the water. The cups 555, 86* are formed ofsheet metal, and on the removal of the caps 42* and gaskets 41* the saidcups may be readily supplied with the filtering material and also bereadily cleaned out whenever necessary.
